The embedded controller used in this module is ST7789V2, an LCD controller with 240 × RGB × 320 pixels, and the pixels of the LCD itself is 240(H) × RGB × 280(V), so the internal RAM of the LCD is not fully used.

This LCD supports input color formats of 12-bit, 16-bit, and 18-bit per pixel, which are RGB444, RGB565, and RGB666. This demo example uses the RGB565 color format, which is also a commonly used RGB format.

The LCD uses a four-wire SPI communication interface, which greatly saves GPIO ports with faster communication speeds.

The resolution of this module is 240 (H) x RGB x 280 (V), but due to the four round corners (see specifications for dimensions), some parts of the input images may not be displayed.
